Ranging in age from 8 through 21 years, the musicians of the four ensembles are selected by competitive audition and come from the Delaware Valley and beyond. The Philadelphia Youth Orchestra has represented the United States on five continents and has visited more than 20 countries including China, Russia, Australia, Great Britain, Jordan, Israel, Brazil, Venezuela, and most of the countries of Eastern and Central Europe. PYO alumni currently serve in all but a few of the top 20 professional US orchestras, including over 12 in The Philadelphia Orchestra alone.
The four ensembles present a full season of concerts each year.
